A Gauge-Mediated Embedding of the S-MSSM

TL;DR

This paper presents a gauge-mediated embedding of the S-MSSM that naturally addresses the little hierarchy problem, allowing the Higgs mass to exceed 114 GeV with minimal tuning and maintaining key supersymmetric features.

Contribution

It introduces a novel gauge-mediated embedding of the S-MSSM that solves the little hierarchy problem without tuning other parameters.

Findings

Higgs mass can be raised above 114 GeV

Top squarks remain below the TeV scale

Perturbative unification is maintained

Abstract

We embed the S-MSSM -- a singlet extension of the minimal supersymmetric standard model with an explicit mu-term and supersymmetric mass term -- in a gauge-mediated supersymmetry breaking scheme. We find that by absolving the singlet of its responsibility for solving the mu-problem, we are instead able to solve the little hierarchy problem naturally. Specifically, we find that even with a minimal embedding of the S-MSSM into a gauge-mediated scheme, we can easily raise the lightest Higgs mass above 114 GeV, while keeping top squarks below the TeV scale, maintaining perturbative unification of the gauge couplings, and without tuning the other parameters of the model.
